Why Does This Property Have a F Rating?
This semi-detached house is located in SWINDON, SN3 1AG. The property offers 58m² (624 sq ft) of modest-sized living space with 4 habitable rooms. It is a post-war property from the mid-20th century. Currently rated F (22/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a B rating (88/100). The walls feature cavity wall insulation for improved thermal efficiency. The loft insulation is rated very good, meeting or exceeding the recommended 270mm depth for optimal thermal performance. Double glazing is installed, though the efficiency rating suggests older units. Modern low-E double glazing can be up to 40% more efficient than units installed before 2002. Estimated annual energy costs are £1410, comprising £1036 for heating, £337 for hot water, and £37 for lighting. The property produces 5.6 tonnes of CO2 per year, which is moderate for a UK home.
